TFT-screen: hom, hauj lwm, yam ntxwv

Nyob rau hauv niaj hnub khoom vaj khoom tsev massively siv hais xws li TFT-cov ntxaij vab tshaus. Lawv muaj peev xwm yuav nrhiav tau nyob rau hauv ib tug ntau yam ntawm hom ntawm pab kiag li lawm: computer qhia, xov tooj ntawm tes cov ntxaij vab tshaus, ntsiav tshuaj, ATMs, raws li zoo li ntau lwm pab kiag li lawm. Yuav ua li cas hom ntawm technology, dab tsi yog cov kev pab cuam? Nyob rau hauv no tsab xov xwm, peb yuav kawm txog dab tsi tshwm sim tawm ib TFT-screen, lawv hom thiab zoo.

Nyias-zaj duab xis transistor (TFT), uas txhais ua lus Askiv txhais tau tias nyias-zaj duab xis transistor. Cov ntsiab yog ua los ntawm nyias zaj duab xis thickness ntawm 0.1-0.01 micrometer. Rau ntau tus neeg, LCDs yog txuam nrog ib tug ca-screen TVs, phau ntawv sau, camcorders, thiab lwm tus neeg. Tam sim no TFT-qhia yog yus muaj los ntawm ib tug muaj zog qauv, siab brightness, muaj peev xwm ua hauj lwm tshaj ib tug ntau ntau yam kub. Kev siv cov no technology yog tau txo qhov nyhav, qhov ntev thiab lub hwj chim khoom.

Tus thawj kua siv lead ua matrix nyob rau hauv 1972. Txij thaum ntawd los, cov technology tau zoo heev evolved thiab hloov. Niaj hnub no muaj ntau ntau hom TFT-saib :

1. TN TFT - qhov no hom ntawm cov xim screen TFT (thawj technology, uas nyob rau hauv kev ua lag luam kua siv lead ua qhia) raws cheapness. Qhov tsis zoo muaj xws li xim distortion, qhov uas tsis muaj duab zoo, kaj thiab heev hnov "tawg" pixels.
2. Super Fine TFT, lub TFT-qhia yog yus muaj los ntawm ib tug tshaj plaws saib lub (170 degrees), thiab siab xim rendition, teb lub sij hawm yog 25 ms, lub "tawg" pixels yog dub, ntsig txog, yog tsis tshua pom.
3. Super IPS, Advansed SFT - muaj ib lub ci, high-zoo dluab, xim distortion yog yuav luag tsis muaj zog saib lub, siab txhais dluab.
4. UA-IPS, UA-SFT - muaj ib tug uas tsis muaj distortion ntawm cov kis cov dluab ntawm ces kaum sib txawv. Cov qhia yog yus muaj los ntawm nce transparency vaj huam sib luag thiab nthuav xim gamut nrog ib theem siab ntawm brightness.
5. MVA, lub ntsiab kom zoo dua ntawm no technology - yog qhov tsawg kawg nkaus teb lub sij hawm, thiab siab zoo. Qhov tsis zoo yog tus nqi.
6. PVA - ntsug kev tso kawm ntawm microstructural LCD.

Nruam txoj kev loj hlob ntawm TFT-technology yuav tshuam txo tau tus nqi ntawm zus tau tej cov xws qhia. Ib qho tseem ceeb nyob rau hauv ntau yam kom nquag plias matrix nyob rau hauv lub lag luam yog qhov yooj yim ntawm fabrication. Niaj hnub no, kov screen (TFT) - qhov no yog ib qho tshaj plaws, thiab nees nkaum xyoo dhau los, nws yog "kim Exotics." Lub rov tshwm sim ntawm kev kov cov ntxaij vab tshaus twb preceded los ntawm cov tsos ntawm cov qauv, uas muaj peev xwm ntawm kev khiav hauj lwm nyob rau hauv hnyav tej kev kawm. Cov tshwm sim yog txoj kev loj hlob ntawm TFT-saib uas ke txhais tau tias rau displaying nrig txog kev pom cov lus qhia, thiab cov ntaub ntawv tswv yim txhais tau tias (keyboard). Lub efficiency ntawm xws li ib tug system muab ib tug serial interface xws li. Yuav kom tswj tau thiab txhais Pib ntsais koj teeb ntawm lub sensor thiab "chatter" hluav PIC-controllers siv, lawv muaj peev xwm ntawm muab high-ceev, thiab raug nyob rau hauv kev txiav txim touch cov ntsiab lus.

Nyob rau hauv xaus, peb hais tias lub TFT-technology yuav luag tag hloov lub tshuab nqus tsev raj saib. Rau hnub tim, TFT-lus - nws yog tsis ib tug nplua nuj, tab sis ib tug natural phenomenon.
